Hi folks! Now here is a problem that is plaguing few people with the introduction of vSphere 4. A few people who bought SAN iSCSI storage in the past with their old VMware 3.5 environments find that their hardware is no longer supported in vSphere 4 on the HCL. The hardware might still work, but it isn’t officially supported so it’s hard to get support when running on unsupported hardware.
What do you do with this storage? After all you spent some serious coin to put this storage in your environment and you don’t exactly want to kick it to the curb. In this situation I would recommend repurposing it as secondary storage.
A lot of iSCSI SAN hardware can make for great archival storage and can be repurposed as a destination point for network attached storage backups. Of course then you are faced with replacing your primary storage with something else. I would recommend always purchasing storage from a reputable vendor that stands behind their products and has a good track record of VMware certification for their hardware.
